Charles Spurgeon Commentary Proverbs 27:5

"Better is open rebuke Than love that is hidden." — Proverbs 27:5 (ASV)

That I should love my fellow-man is a good thing; but to have enough love to openly rebuke his faults is a very strong proof of affection, and far better than secret love that is silent when it should speak. And yet, how many people there are who are very angry with you if you give them an open rebuke, and how many there are who are foolish enough to prefer secret love to open rebuke, though they have Solomon's wisdom to teach them better!

Our Lord Jesus Christ has a secret love for his people, yet he never spares them the open rebuke when he knows that it will be good for them.
